摘要： 校园网的传统计费系统无法支持万兆线速,且局限于流量计费或时长计费,不能实现单一用户多连接数的计费和实时流量阶梯计费。为此,设计一种新的校园网万兆双栈认证计费系统。通过改进计费算法模型实现实时流量阶梯计费,使用优化的通用PC 服务器体系结构提高万兆计费网关的转发性能。经校园网部署应用证明,该计费系统可提供万兆双栈链路下用户实时流量阶梯计费和网关高速转发服务,设计的系统已被清华大学校园网采用并取得了较好的使用效果。

Abstract: The traditional accounting systems cannot support 10 Gigabit wire speed and they do not support one account multiple connections and real-time flow step accounting. A new ten Gigabit dual stack authentication and accounting system is designed and implemented,which improves the accounting algorithm model to realize real-time flow step accouting and optimizes the generic PC server’s architecture to improve the forwarding performance of ten Gigabit billing gateway. The campus network application shows that it can provide real-time charging in ten Gigabit dual stack link and fast forwarding service.

Key words: ten Gigabit, dual-stack, accounting system, real-time, flow step accounting, accounting gateway
